Strobe Glitch?

When I logged on today I was expecting to be playing a game that wouldn't give epileptic seizures to some people. (Don't worry, not hatting!) But when I hit 'PLAY' on the log in screen it went to the white background. But not with Kingsisle on it, it was flashing white . I know this isn't a major weird probably ruin the game glitch, just s computer bug, but can you make sure it doesn't happen again? Thanks!
